Subject: [PATCH 2/5] vcc.y - fix infinite loop with lower-case hex digits
|
|
References: https://github.com/libical/libical/pull/354
|
|
|
|
When lower-case hex digits are used in a quoted-printable-encoded
|
|
character, an infinite loop would occur in the vcard parser.
|
|
|
|
"N;ENCODING=QUOTED-PRINTABLE:=c3=a4=c3=b6;=c3=bC=c3=9f\n"
